Question 1.
What does the Soil-Water Characteristic Curve (SWCC) represent?
Show hintHide hint
Think about the pressure and moisture in soil.
Question 2.
What does a steep slope on the SWCC indicate about sandy soils?
Show hintHide hint
Consider how fast different soils hold water.
3Question 3.
What does the SWCC help estimate in relation to plants?
- Soil temperature
- Plant growth rate
- Plant-available water
Show hintHide hint
Think about how plants take up water.
4Question 4.
True or False: Clay soils have a steeper slope on the SWCC compared to sandy soils.
- True
- False
Show hintHide hint
Consider the water-holding characteristics of each soil type.
Question 5.
Using knowledge of the SWCC, design an irrigation plan for a field with both clay and sandy soil. How would you adjust your watering schedule based on the curve?
Show hintHide hint
Recall the differences in water retention as discussed.
Question 6.
Evaluate how climate change could alter the SWCC of local soils and discuss the potential agricultural impacts.
Show hintHide hint
Consider the implications of longer droughts or intense rainfalls based on historical data.
